The tuyere 13 , a fourth air inlet 14 adjacent to the third air inlet 13 , a second air outlet 〇 2 corresponding to the first air outlet ο , and a third air outlet 03 adjacent to the second air outlet 〇 2 . In the present embodiment, the light source support base 214 includes a first holder portion 214a, a second base portion 214b and a third base portion 214c. The second air inlet 12, the third air inlet 13, the fourth air inlet 14, the second air outlet 02 and the third air outlet 〇3 may all be located on the second base 214b. The first body 214a, the second base 214b and the third base 214c are assembled. 12 1326792 PT900 23809twf.doc/p After completion, the accommodating space S ′ is formed. The light source 212 is disposed in the accommodating space s. In detail, the assembly process of the light source 212 of the present embodiment disposed in the light source support base 214 is illustrated as follows. The light source 212 can be first fixed to the third base 214c. Then the first base 214a and the second base 214b can be assembled by screws (not shown). Finally, the light source 212 and the third base 214c and the first base 214a and the second base 214b are assembled together. In this embodiment, after the light source 212 is assembled with the light source support 214, a portion of the first body 214a may be located above the light source 212, and a portion of the third body 214c may be located below the light source 212. One end of the first body 214a away from the shroud 212c can be assembled with the end of the third body 214c away from the shroud 212c. A portion of the second body 214b can be located forward and on both sides of the light source 212 and a portion of the second body 214b can be positioned above the light source 212. It must be noted here that the light source support 214 can have different shapes and assembly methods according to the designer's needs. Here, the light source support base 214 of the present embodiment is merely illustrative and not limiting. FIG. 6 is a schematic perspective view of the light source module of FIG. 2 . For ease of explanation, a portion of the light source support 214 is omitted from Figure 6. Referring to FIG. 2, FIG. 5 and FIG. 6, the air blower 216 is disposed at the second air inlet 12 and outside the accommodating space S. In detail, the blower 216 can be disposed at the second air inlet 12 by a blower duct 216a, and the portion of the blower guide 216a can be disposed through the second air inlet 12. The blower deflector 216a can have a duct hole 216b that can be closely coupled to the first air inlet II. In addition, the axial fan 218 is disposed adjacent to the accommodating space S in the vicinity of the third air inlet 13 and the fourth air inlet 14 at 13 1326792 PT900 23 809 twf.doc/p. In this embodiment, the light source module 210 further includes a flow guiding member 219, and the flow guiding member 219 is disposed at the second air outlet port 2 and located outside the accommodating space S. In other embodiments, the axial fan 218 can be disposed adjacent to the third air inlet 13 and the fourth air inlet 14 and outside the accommodating space s. FIG. 7 is a front elevational view of the light source module of FIG. 6. For convenience of explanation, FIG. 7 omits part of the light source support base 214, the blower 216, and the axial fan 218. Referring to Figures 2, 5, and 7, the blower 216 is adapted to provide a first air flow C1. The first airflow C1 enters the inside of the reflector 212b (see FIG. 2) via the second air inlet L2 and the first air inlet II, and leaves the interior of the reflector 212b via the first air outlet 01 and the second air outlet 〇2. . In particular, in the present embodiment, the first air stream C1 can enter the interior of the reflector 212b via the blower deflector 216a. Since the air guiding port 216b can be closely coupled with the first air inlet port II, the first air current C1 is not leaked from the joint of the air guiding port 216b and the first air inlet port η. Further, the 'axial fan 218 is adapted to provide a second airflow C2 that enters the accommodating space S via the fourth air inlet 14 and a third airflow C3 that enters the accommodating space S via the third air inlet B. The second air current C2 flows through the periphery of the reflecting cover 212b (see Fig. 2) and exits the accommodating space S via the third air outlet 〇3. The third air flow C3 flows along the flow guiding wall W of the air guiding cover 212c, and leaves the accommodating space S via the second air outlet 02. In the present embodiment, with respect to the relative position shown in FIG. 7, the third airflow C3 flows along the deflector wall W. ===τ. The second airflow C3 is shunted on the opposite upper and lower sides of the shroud 212c. . 1326792 PT900 23809twf.doc/p The temperature of the first gas stream C1 flowing through the inside of the reflector 212b is generally greater than the temperature of the third gas stream C3 flowing through the flow guiding wall W of the shroud 212c, and flows through the guide of the shroud 212c. The temperature of the third gas stream C3 of the flow wall w is generally greater than the temperature of the second gas stream C2 flowing through the periphery of the reflector 212b. Since the first airflow C1 flowing through the inside of the reflector 212b and having a relatively high temperature and the third airflow flowing through the deflector wall w and having a lower temperature can be merged at the second air outlet port 2, the first airflow C1 The temperature can be effectively reduced. In addition, since the first airflow C1 and the third airflow C3 flow through the flow guide 219, and then merge with the second airflow C2 flowing through the periphery of the reflector 212b and lower in temperature, the first airflow C1 and the third airflow The temperature of C3 can also be effective & low. It must be noted here that the function of the deflector 219 of the present embodiment is such that the first airflow C, the third airflow C3, and the second airflow C2 can be joined more efficiently. However, the designer can omit the configuration of the flow guide 219 according to the design requirements (for example, the space arrangement 219 is omitted, and the second air outlet 〇 2 is designed to face the second airflow C2 of the light source module 21 from the third air outlet 03. The flow direction of the flow is not shown in the drawings. In summary, the light source module of the embodiment of the invention and the light and projection device using the same have at least one or some of the following advantages: - a third gas stream flowing through the interior of the reflector and having a relatively high temperature and a flow wall and a lower temperature may be merged first, and then the first gas stream and the third gas stream are again passed through the periphery of the reflector and at a higher temperature The second second airflow is low. Therefore, compared with the conventional one, the first airflow, the first flow and the third airflow leaving the light source module can effectively merge 'and reduce the light source module each = 15 1326792 PT900 23809twf.doc/ p The temperature of the tuyere. 2. Since the blower and the axial fan can generate a plurality of different flow directions through the plurality of air inlets of the light source support seat, the airflows of the different flow directions can effectively take away the light source operation. Waste Heat to the external environment. Therefore, the temperature of each component of the light source of the light source module and the temperature of the light source support can be effectively reduced. Second, since the third airflow is shunted on the opposite upper and lower sides of the shroud, φ is The waste heat generated by the heated shroud can be effectively separated by the third air flow, and the second air flow can be the thermal insulation between the shroud and the light source support, so that the light source support is located at the diversion The temperature of the seats on the upper and lower sides of the cover is lowered. 4. Since the third air flow is flowing toward the second air outlet, the inside of the reflector is inside and the first air outlet is separated from the first air flow. The flow of the two air flows leaves and exits by the second air outlet. Therefore, the first air flow is not easy to reverse flow.
